Title: Process for Making Derivatives of Cellulose and the Products of their Transformation.
Inventor: DREYFUS HENRY
IPC: C08B3/06
Filed: 1911-07-05
Granted: 1912-12-23
Abstract: 20,977. Dreyfus, H. July 5, [Convention date]. Acetates and other carboxylates. -Cellulose acetate, insoluble or difficultly soluble in chloroform, but soluble in alcoholchloroform or alcohol-tetrachlorethane, is obtained by treating cellulose or its near. conversion products with 10 per cent or less of sulphuric acid as a condensing-agent, and 1¢ to 3 parts of acetic anhydride per part of cellulose or cellulose derivative employed. If the amount of sulphuric acid exceeds 10 per cent, the amount of acetic anhydride may be increased by an amount not exceeding four times the weight of sulphuric acid employed, and must be increased above the ratio of 2 parts to 1 part of cellulose. The acetic anhydride may be replaced by corresponding amounts of acetyl chloride, or of homologous anhydrides or chlorides. The sulphuric acid may be replaced, in part or entirely, by other condensing - agents or mixtures thereof. The reaction may be carried out in presence or absence of diluents such as glacial acetic acid, or in suspension, and is preferably effected at ordinary temperature. The cellulose employed may be dry or moist, or may be treated before acetylation with a mixture of glacial acetic and sulphuric acids, or may be impregnated with dilute sulphuric acid and then brought to about the normal degree of humidity; the preliminary hydrolysis should not, however, be too prolonged. In some cases, the products are soluble in pure acetone, in others in dilute acetone. Products of varied solubilities are obtained by treating the above-described esters, when precipitated, with dilute organic or inorganic acids or acid salts or mixtures thereof, or by allowing the original acetylating solutions to stand with or without addition of water, acids, or similarly acting agents, the reaction being in each case interrupted when the desired solubility has been attained. There can thus be obtained products soluble in acetone, dilute acetone, alcohol-benzene, alcohol, dilute alcohol, hot water, &c. The products of the above processes may be used in the manufacture of artificial silk, horsehair, or leather, films, celluloid substitutes, coatings, lacquers, insulating-materials, &c. Specifications 21,628 / 01, 24,067 / 06, 5016 / 07, and 14,271/10 are referred to. The Specification as open to inspection under Section 91 (3) (a) describes also the treatment of any cellulose esters insoluble or difficultly soluble in chloroform with organic or inorganic acids or acid salts, or mixtures thereof ; or the acetylating solutions may be allowed to stand, with or without addition of water, acids, &c. ; products of varied solubility are thus obtained as described above. This subject - matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 19,330/05, 26,657/09, and 24,382/10.

Granted: 1913-01-23
Abstract: 2212. Soc. E. & G. Brabant & Vaadier. Dec. 29, 1911, [Convention date]. Threads, gassing.-The means for guiding the thread and the means for shifting it out of or into the gassing-flame &c., on stoppage or starting of the head or of the machine, are independent of one another, the guiding-means being fixed to the burner. The gassing-frame shown comprises bobbin carriers with stop-motions and stop - apparatus described in Specification 1437/12, [Class 120 (ii), Spinning, twisting, &c.], the means for shifting the thread being connected with the stop - motion and stopapparatus of the head. In the form shown in Figs. 1 and 3, the guiding-means is in the form of a pair of glass or enamelled metal plates 4, 5 fixed to the sides of the burner 2 having a suitable orifice 3, the thread 7 passing along V- shaped notches 6 in the plates and over a glass or porcelain pulley 8 arranged higher than the bottom of the notches 6, to the winding-mechanism. A rod 28 fixed to the pendulum 18 is bent at right-angles at 29, 30, the part 30 passing over the thread and constituting the shifting member; when a thread breaks, or the bobbin is completed, or a head or the machine stops, the rod 28 is displaced, and the part 30 pulls the thread out of contact with the flame and in the plane thereof. In a modification, the thread is shifted laterally to the plane of the flame by a rod attached to an arm loosely mounted on the stop-rod 17 of the winding head and loosely jointed by bent lever and stops to the cam-shaft 22 of the stop-motion; the guiding-members are formed of bent rods fixed at each-side of the burner in a plane parallel to the plane passing through the major axis of the burner orifice, the thread passing through eyes in front of and behind the guides and set backwards from the rods so that the thread is well stretched. In a further modification, the thread is shifted laterally to the plane of the flame by the arms 41, 42, Fig. 7, of a fork member attached to an arm 35 fulcrumed on a pivot 43 on the machine frame and carrying a pair of stops 39, 40, between which is located a rod 45 attached to the pendulum 18 of the head. When re-starting, the rotation of the bobbin may be effected an instant before the shifting of the stop-rod 17 by forming the pendulum part 58 curved so that in their normal positions play exists between the pendulum and the axis of the intermediate driving tube.
